To all whom t may concern:

Be it known that l, PATRICK SMITH, a citizen of'the'United States, and a resident oi' Foresthill, in the county of Placer and State ot California, have invented a new and lmproved nFastening Means for 'lire-Grips,y of which the following is a full, clear, and exact description i My invention relates to a means for tastening attachable grips to automobile tires and more particularly the invention' is intended for use in securing a grip of the character disclosed in an application for patent tiled by 126,709. l,

lThe prime object ot the present invention is to provide a fastening means adapted to be disposed transversely beneath the wheelv telly and arranged to be fastened or unfastened with facility and despatch to secure the grip in position or to permit its ready removal.

Reference is to be had to the accompanying drawings forming a part ot this' specili-u cation in which similar reference characters indicate corresponding parts in all the views, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a side^elevation of a portion of a wheel and tire showing my attachment applied thereto;

Fig. 2 is a cross section; p

Fig. 3 is a view taken at the inne side of the ielly showing a face view of my improved fastening means;

Fig. 4 is a detail in section on the line 4-4, Fig. 2.

The grips for which my'fastening means is more particularly intended are separately a plied to the tire in any desired number.

ach grip is composed ot separate curved members 10, the lcurvature corresponding with the curve ont the tire shoe A. Each member 10 of each grip or gripping section in the illustrated exampleis formed with a beveled rib 11. The members 10 of each grip are Hexibly connected through the medium of a transverse cable 12 preferably of wire,

l5@ the cable being accommodated in registering t5 15 of the cable may be soldered.

bores 13 in the respective members 10. The

cable 12 at each end passes through. a block me Dctober 20th, 1916, Serial No. 'y

for' holding it in the latchingposition.

ing through the inner face ot the block 14 to bear gainst the cable. u

To secure the grip in position suitable links or equivalent means are provided at each sideand connected with the 'blocks 14,v

the links or the like at each side being adapted to be secured by my improved fastening means that extend at the inner side Vot the felly B. lin the form shown each block 14 has an arm 17, one arm 17 carrying a link 18 and the opposite arm, a link or strap i9. ll proyide a latch platev 20 adapted to lie against the inner face of the telly B, said plate being pivoted Yat one end as at 21 to the element 19 and the opposite end. ot' said latch plate is adapted to engage a fastener bar 22 having a head 23 which is received between the spaced arms ot' a hooked fork 24 formed on the said latch plate 20. rl`he latch plate 2O is provided with a latching slide 25 which is formed with side Hanges 26 giving the slide guided movement on the said latch plate. rlhe slide 25 is lormed with a longitudinal slot 27 and the plate 29 has a screw 28 extending through said slot and having an enlarged head beneath which the' 'slide is held, said head having opposite 'Hattened sides or otherwise formed to receive a wrench to give the screw a slight turn for permitting the slide 25 to move longitudinally or to bind against the slide 'lhe terminal 29 of the slide 25 adjacent tothe hooked arms 24 is formed on said slide and curved oppositely to the arms 24. 'll'he head till 23 carriesl a loop 3() extending loosely through a transverse hole 31 in said head so that the loop inayohave a swinging movement. The ends of the loop 30 at the sides ot the head 23 extend sudiciently to be enga ed by the hooked arms 24.

ith the describedconstruction the grip vhaving been placed on the tire, in order to fasten the grip the loop 30 is .swung to the dotted linel position indicated in Fig. 2 and the slide 25 is slid in a directionto move the latching terminal 29 thereof away from the hooked arms 24, thereby permitting the head 23 to be passed between the hooked arms and the loop 30 to be engaged by said arms.

-The slide 25 is then moved to bring ,the terminal 29 adjacent to the members 24 and the loop 3() may vthen be swung over the said terminal 29 as indicated in the full line position, Fig. 2. The full line position ot the terminal 29 holds the head 23 and its loop Mitt against retrograde movement. The prime` oflice of the .loop 30 is to eect engagement with the hooked arms 24 and incidentally it j tion will not a ect the fastening since the screw 28 positively holds the slide 25 in proper relation to the hook elements 24. I wish to state in conclusion that lalthough.

.the illustrated example constitutes a practical embodiment of my invention, ll do not limit myself strictly to the mechanical details herein illustrated, since manifestly the'y same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described my. invention, l claim as new, and desire to secure by Let; ters Patent:

1. lThe herein described' fastening means for tire grips, including a latch plate adapted at one end for connection with the .grip at one side of the latter, spaced hooked arms on the opposite end of said plate, a latch slide on said plate, that end of the slide adjacent to the said hooked arms having a latching terminal curved oppositely to the said arms, means to lock the said slide Laeaaae against movement, a bar adapted atene end for connection with the grip at the oppositev f able with the latter adjacent to or from the hooked arms, and adapted to extend through the said loop.

2. ln a fastening means ofthe class described, a latch element adapted to'be secured at one end to 'the grip at one side of the latter and formed at the opposite end with spaced hooked arms, a latch bar adapted to be secured to the grip at the opposite side from said element, said bar having a head receivable between said hooked arms, a sliding member on the' said latch element and formed With a latching terminal to co-actwith said hooked arms, and a transthe said hooked arms when the head is positioned between the latter.
